Swift 3.1 aims to maintain source compatibility with Swift 3.0 while adding minor language enhancements, improvements to the Swift Package Manager, better Linux support, and general fixes to the compiler and standard library, with a planned release in spring 2017.

All language and API changes must go through the Swift Evolution process, and pull requests for the branch require detailed explanations, risk assessments, and reviews by code owners and release managers.
